Overview
The Traxxas Velineon Cooling Fan Kit with Shroud (TRX3456) is an essential upgrade for RC enthusiasts running brushless motors in high-performance RC cars. Whether you're piloting a Traxxas Mini XRT VXL-3S, Traxxas Slash VXL 1/10 4x4 Short Course Truck, or any vehicle fitted with compatible Velineon brushless motors, this cooling system will help you achieve longer run times and more consistent performance during intense driving sessions. Designed for serious RC hobbyists across the UK who demand reliability and extended motor life, this fan and shroud assembly works in perfect harmony with your brushless motor setup to maintain optimal temperatures even during demanding, extended use.
If you're running a brushless RC car or truck, motor temperatures can rise significantly during aggressive driving, particularly during competition events or extended basher sessions. The Traxxas Cooling Fan Kit addresses this challenge directly by actively drawing heat away from your Velineon motor, allowing it to run cooler for longer periods. This translates to better throttle response, more predictable handling characteristics, and importantly, a longer lifespan for your expensive brushless motor investment. The fan and shroud combination is engineered to integrate seamlessly with existing Traxxas setups, making it an intelligent upgrade for anyone looking to maximise their RC car's potential.
RC enthusiasts throughout the UK have long recognised that proper thermal management is crucial for competitive performance and motor longevity. This cooling fan kit represents genuine Traxxas engineering designed to work with their brushless motor ecosystem, giving you the confidence that you're investing in a proven, quality solution. Whether you're a weekend basher or a more serious racer, this cooling upgrade is a straightforward way to protect your motor investment and enjoy longer, more consistent running sessions.
Key Features
- Active Cooling Shroud Design — The integrated fan shroud actively draws heat away from your Velineon brushless motor during operation, maintaining lower temperatures that preserve motor performance and extend the lifespan of your investment significantly.
- Compatible with Velineon 3500 and 540XL Motors — This cooling kit is specifically engineered to work with Traxxas Velineon 3500 and 540XL brushless motors, ensuring perfect fitment and optimal thermal performance for these popular motor options.
- Fits #3351R and #3461 Motors — The kit is fully compatible with Traxxas model #3351R and #3461 brushless motors, making it suitable for a wide range of popular RC vehicles including the Mini XRT VXL-3S and Slash VXL 1/10 4x4 Short Course Truck platforms.
- Extended Run Times — By maintaining cooler motor temperatures during demanding driving conditions, this cooling system allows you to enjoy longer, more consistent run times before thermal throttling or performance degradation occurs.
- Mounts to #3458 Heat Sink — The fan shroud attaches securely to the separate Traxxas #3458 heat sink (sold separately), creating a complete cooling solution that integrates cleanly with your existing motor setup.
- Genuine Traxxas Engineering — This is an official Traxxas component manufactured to the same high standards as the rest of your RC car, guaranteeing compatibility, durability, and reliability you can depend on.
- Simple Installation — The shroud screws directly onto the 3458 heat sink with straightforward assembly, requiring no special tools or modifications to your existing RC setup.
Technical Performance
The Traxxas Velineon Cooling Fan Kit represents a thoughtfully engineered approach to thermal management for brushless RC vehicles. Thermal performance is critical in modern RC cars, particularly when running demanding, extended sessions where continuous high-throttle driving can push motors to their thermal limits. The cooling fan and shroud combination works by forcing air across the motor windings and through the shroud structure, actively removing heat that would otherwise accumulate and cause performance loss through thermal throttling. The fan is specifically designed to work in conjunction with the Traxxas #3458 heat sink, which itself provides additional surface area for dissipating motor heat. When used together, these components create a comprehensive cooling solution that maintains optimal operating temperatures. This is particularly important for competitive RC racing, where consistent motor performance across multiple heats or races can determine success. The engineering emphasises durability and long-term reliability, with the shroud constructed to withstand the demanding conditions of off-road RC driving. Whether you're running a Mini XRT VXL-3S, a Slash VXL Short Course Truck, or another vehicle equipped with compatible Velineon motors, this cooling system integrates seamlessly into your setup. The active cooling approach means you'll enjoy more consistent throttle response, better acceleration characteristics, and importantly, extended motor lifespan compared to running without cooling.

Frequently Asked Questions
- Which RC cars and trucks is this cooling fan kit compatible with? — This cooling fan kit is designed to fit Traxxas vehicles equipped with compatible Velineon brushless motors, including the Mini XRT VXL-3S in all colour variants (green, orange, red, and blue) and the Slash VXL 1/10 4x4 RTR Short Course Truck in all colour options (blue, green, orange, and red). It also works with any RC car or truck using Velineon 3500 or 540XL brushless motors. If your vehicle features a compatible motor, this cooling kit should work with your setup.
- Do I need to purchase anything else to use this cooling fan kit? — Yes, you will need the separate Traxxas #3458 Heat Sink (sold separately) to properly mount the cooling fan shroud. The shroud screws onto this heat sink, so both components together form the complete cooling solution. Your vehicle must also be equipped with a compatible Velineon brushless motor.
- How much longer will my motor run with this cooling fan installed? — The exact improvement in run time depends on your driving style, ambient temperature, and throttle usage, but most users report noticeably longer run sessions before experiencing thermal throttling or performance loss. The cooler your motor runs, the more consistently it will perform across extended driving sessions, and the longer its operational lifespan will be.
- Will this cooling fan kit work on any brushless motor? — No, this kit is specifically engineered for Traxxas Velineon brushless motors, including the 3500, 540XL, #3351R, and #3461 models. It is not compatible with motors from other manufacturers or non-Velineon Traxxas motors. Always confirm your motor model before purchasing.
- Is this cooling kit suitable for beginners? — Yes, this is an excellent upgrade for RC enthusiasts at all skill levels. Whilst beginners may not need cooling immediately, adding this kit is straightforward and provides immediate benefits in terms of motor longevity and consistent performance. More experienced drivers and competitors will especially appreciate the extended run times and thermal management this provides.
- How is this cooling fan powered? — The cooling fan operates from your RC vehicle's main power system, receiving power through your ESC and main battery, so it runs whenever your vehicle is operational without requiring any additional battery or power source.
- Can I use this cooling kit in wet conditions? — The cooling fan is designed for typical RC off-road conditions. Whilst Traxxas products are engineered robustly, you should always check your specific vehicle's weatherproofing specifications and avoid submerging or heavily spraying the fan motor itself.
